Cars in Hong Kong are mostly right-steering, so by reducing the right front door and make a larger left one instead it would be more convenient to passengers. Plus a fold-able vice-driver seat like those in the cinema, single front door will not make the driver feel inconvenient when getting off the car. A gull-wing front door with electric sliding back doors no only brings out the aesthetic tone of the car but also safety. With those specially-designed doors, the spaces needed for parking are reduced, making the car more suitable for small and cramped city like Hong Kong. An djustable ramp under the vice driver seat, for disables to get on the car with ease.
